CORRUGATED RADIATOR.

SPECIFICATION forming part of Letters Patent No. 794,315, dated July 11,1905.

Application filed June 14, 1904- Serial No. 212,569.

To all who/11, it may concern:

Be it known that I, WVILLIs E. RoYs, a citizen of the United States, anda resident of the city of New York, Richmond Hill, borough of Queens, inthe county of Queens and State of New York, have invented a new andImproved Corrugated Radiator, of which the following is a full, clear,and exact description.

The invention relates to metal radiators for steam-heating; and itsobject is to provide a radiator that will take up very little room andno floor-space.

My invention hanging on the wall and being made of sheet metal is not soheavy as cast-iron and can be easily fastened to the Wall.

The invention consists of novel features and parts and combinations ofthe same, as will be more fully described hereinafter and then pointedout in the claims.

A practical embodiment of the invention'is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a front elevation of my improved radiator. same, thesupporting-pipe being shown in section. Fig. 3 is partly a top plan viewand partly a horizontal sectional view of the same; and Fig. 4 is adetail view on a larger scale, being partly a top plan view and partly ahorizontal section.

The steam-pipe 1 has a valve 2 and a horizontal connection or portion 3,which is supported at a suitable height above the floor, and is hereshown as provided with perforations.

The radiator is made of corrugated sheet metal, the central portion ofwhich is flattened and bent around the pipe 3, the side and top edges ofthe wall B thus formed being flattened, as at D F, and united together.The corrugations 4 in the front and rear Walls and which extend abovethe pipe 3 form steamspaces between said walls and increase theirsuperficial area. Steam is discharged from Fig. 2 is an end elevation ofthe the said pipe 3 through its perforations or openings into the saidsteam spaces. The corrugations of the respective walls register, andsaid walls are secured together between the corrugations by means ofrivets C. On the upper edge of the radiator is placed a cap or rail E,which is preferably of the construction shown, and is attached to abracket G, which is secured to and projects from the wall. Thecorrugations in the walls of the radiator besides providing thesteam-spaces therein and greatly increasing the superficial areasthereof also greatly strengthen the construction of the radiator.

My improved radiator is exceedingly compact, cheap, light, efficient,does not obstruct the floor and enables the floor to be readily cleanedunder it.

I elaim- 1. In combination with a supporting supply-pipe, a radiatormade of sheet metal and having a portion bent around the said supportingsupply-pipe, the walls thus formed having their edge portions flattenedand united together and their intermediate portions corrugated to formsteam-spaces between said walls, a cap on the upper edge of theradiator, and a supporting-bracket attached to said cap.

2. A radiator made of sheet metal, doubled to form a cylindrical portionand side walls above said cylindrical portion, said side walls beingcorrugated to form steam-spaces between them, and a supporting andsteam-supply pipe extending through and fitting in said cylindricalportion of the radiator, said pipe having openings to discharge steaminto the steam-spaces of the radiator, substantially as described.

3. In combination With a supporting-pipe, a radiator made of sheet metaland having a portion bent around the pipe.
